Device for reverse-twisting stranding elements

Abstract

A device for the reverse-twisting of stranding elements (4), comprising a stationary guide disk (1) and a twisting disk (2) located at a distance from the guide disk and able to rotate around its axis. At least one filament-shaped, tension-proof support element (7) is located between the guide disk (1) and the twisting disk (2). At least one holding element (5) is mounted on the support element (7) and is located at a distance from the guide disk (1) on one side, and from the twisting disk (2) on the other. The holding element (5) contains axial passage holes (6) for the stranding elements (4). The ends of the support elements (7) are affixed in holders (9), which are able to tilt and/or rotate with respect to the twisting disk (2).

       2. A device as claimed in claim 1, wherein said holders are able to tilt in a vertical and horizontal direction. 
     
     
       3. A device as claimed in claim 2, further comprising universal joints for mounting said holders. 
     
     
       4. A device as claimed in claim 3, further comprising axial and radial bearings for mounting said holders. 
     
     
       5. A device as claimed in claim 4, wherein ends of said at least one support element are bent inside said holders and are clamped in said bent condition. 
     
     
       6. A device as claimed in claim 5, wherein said at least one support element comprises a cable made from a number of twisted or bunched individual metal wires. 
     
     
       7. A device as claimed in claim 6, wherein the cable is plastic coated. 
     
     
       8. A device as claimed in claim 7, wherein the plastic coating penetrates into a center of the cable between the individual metal wires. 
     
     
       9. A device as claimed in claim 6, wherein said at least one holding element comprises a plurality of holding elements that are separated by small tubes surrounding said at least one support element. 
     
     
       10. A device as claimed in claim 9, wherein said small tubes are made of wound steel wires having an external protective sheath. 
     
     
       11. A device as claimed in claim 9, wherein at least said small tubes at the ends of said at least one support element adjacent to said holders are made of wound steel wires having an external protective sheath. 
     
     
       12. A device as claimed in claim 6, wherein said at least one holding element is at least partially made of ceramic. 
     
     
       13. A device as claimed in claim 6, wherein said at least one holding element is at least partially made of a highly abrasion-resistant plastic. 
     
     
       14. A device as claimed in claim 6, wherein said at least one support element is prestressed. 
     
     
       15. A device as claimed in claim 14, wherein the prestressing of said at least one support element is performed with a tensioning system having at least one linear compressed air cylinder. 
     
     
       16. A device as claimed in claim 14, wherein said at least one support element comprises a plurality of support elements, and wherein the prestressing of each one of said plurality of support elements is performed with a tensioning system having a plurality of linear compressed air cylinders, wherein one linear compressed air cylinder is provided for each support element. 
     
     
       17. A device as claimed in claim 1, wherein said at least one support element comprises a plurality of support elements, and wherein at least one spacer ring is provided for spacing said support elements. 
     
     
       18. A device as claimed in claim 1, wherein: said at least one support element comprises a plurality of support elements;   said at least one holding element comprises a plurality of holding elements; and   wherein 60% to 80% of said holding elements are spacer rings for spacing said support elements.   
     
     
       19. A device as claimed in claim 1, wherein ends of said at least one support element are bent inside said holders and are clamped in said bent condition. 
     
     
       20. A device as claimed in claim 1, wherein said at least one support element comprises a cable made from a number of twisted or bunched individual metal wires. 
     
     
       21. A device as claimed in claim 20, wherein the cable is plastic coated, and wherein the plastic coating penetrates into a center of the cable between the individual metal wires. 
     
     
       22. A device as claimed in claim 1, wherein said at least one holding element comprises a plurality of holding elements that are separated by small tubes surrounding said at least one support element. 
     
     
       23. A device as claimed in claim 22, wherein at least said small tubes at the ends of said at least one support element adjacent to said holders are made of wound steel wires having an external protective sheath.
